Usage: A left click on the window changes the view between inner and outter
planets. A left click on the date increases the day/month/year. A right
click on the date does the opposite. Click the right mouse button on the
solar system to reset the date to the current date (which is in Universal Time).

Type "make" to build it and then ./wmSolar to run it.

wmSolar uses a bit modified AstroOps by Mark Huss which is based on
Bill Gray's open-source code at projectpluto.com.
